Reducing temporal redundancy in MJPEG using Zipfian estimation techniques

Abstract

Abstract—Motion JPEG simply compresses each frame in a video sequence using JPEG still image compression standard. This video codec satisfies power consumption and real-time properties of embedded systems while having very low complexity. However, the downside is its inefficiency in reducing the bit-rate because there are still redundancies between encoded frames. In this paper, we focus on reducing temporal redundancies in MJPEG using a motion detection algorithm, called Zipfian estimation. The Zipfian estimation helps ...
